Suppose there are three stars in space, each moving at 100 km/s. star a is moving across (i. e., perpendicular to) our line of sight, star b is moving directly away from earth, and star c is moving away from earth, but at a 30° angle to the line of sight. from which star will you observe the greatest doppler shift? from which star will you observe the smallest doppler shift?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
